tion Relating to Phonograph-Stop Devices,

of which the following'is a specification,

taken in connection with the accompanying drawing, which forms'part ofthe same.

This invent-ion relates especiallyjto phono- "graph stopdevices adaptedto cooperate with the usual disk phonographs and comprising a brakelever cooperating with the turntable of the machine and having anactuating spring normally holding a pro- "ectin catch on said brakearmin contact with a latch arm which may also be pivoted beneath theturntable and having a part projecting therefrom so as to cooperate withand be actuated by the usual tone arm of the phonograph. An adjuster maybe used in connection with the latch arm to regulate the part of therecord at which the stop device operates and if desired, a contact armmay be used in connection with the adjuster so as to be engaged by thetone arm and operatethe brake by releasing. thelatch.

In the accompanying drawing showing several illustrative embodiments ofthis in vention, Figure l is a plan view, parts heingbroken away. Fig. 2is a side elevation, and F is 3 is an enlarged elevation showing amodified form of the device.

In the embodiment of the invention shown in Figs. 1 and 2 the top 1 ofthe motor casing may be of any usual construction and the rotatingturntable 4 may be mounted above th same in the usual way so as toproperly support the phonograph record disk The brake lever 19 may beconreni'ently'pivoted beneath the turntable by securing it by the pivotscrew or pin 17 in the top so as to bring the brake 20, of

leather or other suitable material, into cooperation with any conven entpart ofthe phonograph mechanIsnn-such as the depending edge tiangefQ'So1"? thje tuintable. The

brake .may hare.- a suitable actuating spring 1 5.whichmaybeconveniently connected to Specification of Letters Patent. PatgntedApplication filed Apri1 3, 1912. Serial No. 688,129.

13 which may be conveniently pivotedabout the pivot screw 12 beneath theturntable, suitable metallic washers being used, if de-' thebrake arm 16and to a cooperating latch sired, below these pivoted parts and also, in

some cases, above them. By arranging this actuating spring substantiallyin line with the latch it normally holds the same in contact with thelatch pin 29 so asto bring the end of this latch into engagementwith anysuitable portion of the brake arm such for instance as the upwardlyprojecting catch lat adjacent the end of the same. In this way thespring powerfully actuates "the brake so as to bring the turntable torest after a partial revolution which serves-to gradually absorb itsmomentum while at'the same tune t-hisspring interposes little jre'sistance to the movement of the latch arn l-away from the catch during thistripping orstop-' ping action. The latch arm ll -is preterably.

extended so as to projectsomewha beyond the turntable and be actuatedfrom the usual tone arm 2 which 1s swung over the record in anyusualway.

If desired the stop device may comprise a records in which thesound-groove extends inward to varying dlstan'ces'as is usual. For

this purpose the adjuster 9 may, if desired,

be provided with a wedge shaped end .00- operating with the latch armandpreferably having fiat edges of about the height. of the.

latch arm, these edges being conveniently formed by stampin or bendinguptheedge portions of a fiat giece of metal. This ad-, juster may beconnected by the pivot 25 to the adjusting lever 2a which may be mountedso as toswing' aboutthe pivot screw beneath the turntable and have itsindlcator by the needle attached togthe sound box 3 suitable adjustercooperating with the latch arm in such way as to regulate't-he' part of;the record at which the'stop" device is actu- "ated, and thus make thedevice adaptable to and handle 26 cooperate with a suitable graduatedscale 27'located at a convenient distance beyond the 'edgeof theturntable,

and preferably on the opposite side of the axis of the turntable fromthe. adjustingleverv pivot 23 so that the lever end moves substantiallysymmetrically over this scale. A

stop pin 22 may be used to limitthe move-' mentof the adjusting leverand a suitable stop pin 10 may be used to prevent the adjuster frommoving away from the latch arm to anundesirable extent.

If desired a suitable contact arm 7 may be mounted in any desired wayfor cooperation with the tone arm and the other parts to be actuatedtherefrom, and this contact arm may if desired, be pivoted about thepivot screw 12 of the catch and be provided with a contact piece 6projecting upward into the path of the tone arm itself so as todisengage the latch by swinging the latch arm and inw terposed adjusterover when the tone arm engages the contact piece, the contact arm, ofcourse, having in this case a suitable projection on the underside toengage the ad juster such for example as a short extension of thecontact piece or rod 6. The contact arm preferably has a relativelybroad pivot-al portion cooperating with the fiat latch so as to minimizetwisting when the parts are actuated although a light pressure issufficient to disengage the latch arm from the catch of the brake armwhich thereupon swings the latch inward so as to relieve the contactpiece from further pressure from the tone arm, the direction in whichthe parts move in stopping the turntable, being indicated by the arrowsin Fig. 1. The device may be readily reset when the tone arm is swun outinto the usual position and a new record applied to the turntable, byforcing the setting handle 21 inward which swings the brake arm outwardsufiicient-ly to allow the latch to be swung upward by the actuatingspring into contact with the latch pin 29 so that on releasing thesetting handle the actuating spring draws thecatch 14L- against thelatch so as to disengageably hold these parts in the normal setpositions shown in Fig. 1, the brake being thus released from contactwith the turntable which thus begins to rotate in the usual way to playthe record. I

Since the sound grooves terminate at different distances from thecenters of various records it is desirable to indicate on each recordthe location of the inner end of the sound groove atwhich pointthestopping device should be actuatedand for this purpose the records maybe measured and marked to correspond with the designatmns on the scale:27 which may be arbitrary orinwardly swinging tone arm when the needlecontactpiece may directly engage the adjuster as is shown in Fig. 3. Inthe modification of the device therein indicated the contact arm 30 maybe connected to the tone 7 arm 2 by securing the plate on the end of thecontact piece to the tone arm in any desired way such as by the screws32. The contact arm is thus in the path of the aduster 8 so as to engagethe same when the tone arm is moved inward to the end of the soundgroove so as to force the adjuster and cooperating contact arm 11 oversufiiciently to stop the machine.
